The functions of twelve school nurses in a large metropolitan school district were examined in relation to utilization of health services and student time lost from school using health problem categories. Findings suggest absentee data and utilization are valuable outcome measures supporting the importance of school health programming.
Since 15 years, the ASMT (Association for the promotion of sports in enterprises) has been trying to demonstrate that physical activities is a health factor for workers and their enterprises. Few studies (1980-1990) in individual enterprises (Alsthom, IBM, Aérospatiale, Peugeot...), and a national one (1985, 1,600 sportsmen) have shown the relationship between exercise and a lower absenteeism. These results were confirmed by a randomized national controlled study in 1990-1991. With the assistance of 115 work-doctors, the ASMT included more than 22,000 workers: 38% of them had physical activities (ASMT 1: 1 hour a week, ASMT 2: 3 hours a week, ASMT 3: competitors), and 62% had none. Exercisers have less industrial injuries than sedentary people (3.78% vs 4.52%. p. < 0.001) and less absences for illness (26.4% vs 30.8%. p. < 0.001). The duration of their absences are shorter for industrial injuries (sedentary people: 27.9 days, ASMT 1: 27.1 days, ASMT 2: 25.5 days, ASMT 3: 24.6 days) and for illness (sedentary people: 23.6 days, ASMT 1: 19.1 days, ASMT 2: 17.4 days, ASMT 3: 15.3 days).
Various administrative techniques used to bring staff pharmacists in a decentralized, satellite pharmacy system into the managerial decision-making process are discussed. These techniques include a staff pharmacist on-call procedure to discourage absenteeism, and the concept of a head pharmacist to serve as a link with departmental administration. The head pharmacist works in the satelite pharmacy, is responsible for its daily operation and is the spokesman for the satellite. Active roles for the head pharmacist in the selection and evaluation of technicians are outlines. Management skills are developed in head pharmacists through a program of special classes and discussion groups. It is concluded that this program has improved the credibility of administrative decisions and has tapped an underused source of ideas and talent.
Cost problems in business, industry and government service force everyone to probe into the economy of traditional patterns of work and procedures. Occupational medicine is no exception. However, there has been a lack of criteria for assessing the economic aspects of occupational medicine. We are therefore suggesting an approach. Caring for the "human capital" factor is a cornerstone of free socioeconomy. Workers should not only be suitably qualified for their job but there must be the smallest possible minimum of absenteeism. Occupational medicine can do something to positively influence the following factors: by preventing incapacity to work by preventing job accidents and professional diseases by reducing the time required to cover distances between or within workflow phases or stages by reducing waste of time by waiting. Model calculations, based on highly plausible basic postulates, show that fully integrated occupational medical services are throughout economic and cost-saving. Using a concrete example, we arrived at a cost/benefit ratio of 1:2 while confining ourselves to benefits attainable within a relatively short time. We ignored other, future benefits requiring certain preventive measures, as well as other parameters that are difficult to assess, such as corporate identity. At present occupational medicine faces a certain amount of identity crisis which should not be counteracted by pointing to legislation that justifies its existence, but rather by proving that it is indeed highly economical because it saves time and money.
The work concentrates on low back pain syndrome which has become an important social problem because of its frequent occurrence in the general population and different etiological factors. The syndrome also belongs to major causes of long-term sickness absenteeism and permanent work disability. The author discusses both nonoccupational and possible occupational factors inducing the disease, conditions for correct diagnosis of low back pain syndrome as a paraoccupational disease and preventive methods including technical, organizational and medical aspects.
BACKGROUND AND OBJECTIVES: Hand washing prevents communicable illness. We evaluated the effect of a mandatory, scheduled hand-washing program in elementary school children on absenteeism due to acute communicable illness. METHODS: The study was conducted at Trombley Elementary School in Grosse Pointe Park, Mich. The intervention group, approximately half of the school children (n = 143, including all grades 1-5), washed their hands a minimum of four scheduled times a day. The control group (n = 162) continued hand-washing practices as usual. RESULTS: Of the 37 school days examined, children in the hand-washing group were absent fewer days than the control group due to all acute communicable illness (relative risk = .75). There were less days of absence due to gastrointestinal symptoms (relative risk = .43). The difference in absence due to respiratory symptoms was not statistically significant. CONCLUSIONS: A scheduled hand-washing program will reduce acute communicable (gastrointestinal) illnesses in elementary school-age children.
The aim of the study was to analyse the incidence of accidents at work in the Szczecin voivodship in 1982-94. In the analysis the number of workers employed in the national economy and the number of accidents were taken into account. The rate of accidents at work (the number of accidents/1,000 workers in /1000), the accident severity (the number of work disability days/the number of accidents at work), the rate of fatal accidents at work (the number of fatal accidents/1,000 workers in /1000), the rate of acute injuries (the number of severe injuries per 1,000 accidents at work) were determined. The rates of accidents at work and fatal accidents in the Szczecin voivodship were compared with the rates in the whole country during the same period. The number of workers employed throughout the period between 1982-94 maintained at almost the same level. It increased mostly in 1990 and then decreased (Table 1). The largest number of accidents was registered in 1983 and the lowest in 1994. During the period studied the number of fatal accidents and absenteeism due to accidents at work decreased, however, the rates of fatal accidents and acute injuries increased. The rate of accidents at work in the Szczecin voivodship during the years 1982-94 was higher than in the whole country.
In this study results of a survey taken of persons insured under the public health care system were presented. The main objective of the survey was to determine the health of the insured on the basis of their subjective data, as well as to assess their prevention behaviour and their wish that the health insurance should offer prevention programmes. In addition, the health insurance provided data on how often the insured persons were unable to work for health reasons during a period of seven years. The data of work absenteeism are used to divide the group of respondents according to their health. To determine internal consistency it was first investigated whether persons with periods of disablement during one year (cross-section) also had long periods of disablement in the years before or after (longitudinal section). It was found that in the cross-section, persons with serious health problems (more than six weeks of disablement) differed little from those with average disablement periods (from one to six weeks) in the long-term development of disablement. The study also examined the correlation of periods of disablement and subjective data (validity). A mean correlation was found between the respondents' subjective assessment of their health and the length of disablement periods. There was also a significant negative correlation between internal health locus of control beliefs and the length of disablement. The results are discussed, and the ways and limits of using periods of disablement for empirical studies are presented.
OBJECTIVE: To estimate the overall economic burden of pneumonia from an employer perspective. METHODS: The annual, per capita cost of pneumonia was determined for beneficiaries of a major employer by analyzing medical, pharmaceutical, and disability claims data. The incremental costs of 4036 patients with a diagnosis of pneumonia identified in a health claims database of a national Fortune 100 company were compared with a 10% random sample of beneficiaries in the employer overall population. RESULTS: Total annual, per capita, employer costs were approximately 5 times higher for patients with pneumonia ($11 544) than among typical beneficiaries in the employer overall population ($2368). The increases in costs were for all components (eg, medical care, prescription drug, disability, and particularly for inpatient services). A small proportion (10%) of pneumonia patients (almost all of whom were hospitalized) accounted for most (59%) of the costs. CONCLUSIONS: Patients with pneumonia present an important financial burden to employers. These patients use more medical care services, particularly inpatient services, than the average beneficiary in the employer overall population. In addition to direct health care costs related to medical utilization and the use of prescription drugs, indirect costs due to disability and absenteeism also contribute to the high cost of pneumonia to an employer.
The irritable bowel syndrome is a common disorder associated with a significant burden of illness, poor quality of life, high rates of absenteeism, and high health care utilization. Management can be difficult and treatment unrewarding; these facts have led physicians and patients toward alternative therapies. We explored a variety of treatments that exist beyond the scope of commonly used therapies for irritable bowel syndrome. Guarded optimism exists for traditional Chinese medicine and psychological therapies, but further well-designed trials are needed. Oral cromolyn sodium may be useful in chronic unexplained diarrhea and appears as effective as and safer than elimination diets. The roles of lactose and fructose intolerance remain poorly understood. Alterations of enteric flora may play a role in irritable bowel syndrome, but supporting evidence for bacterial overgrowth or probiotic therapy is lacking.
BACKGROUND: Asthma is the most common chronic condition of childhood and a common reason for school absenteeism and use of school health services. Unrecognized but symptomatic childhood asthma may be adding to this school burden. OBJECTIVE: To evaluate the effectiveness of school-based asthma screening in identifying children at high risk for unrecognized asthma and facilitating new asthma diagnoses. METHODS: A controlled trial of school-based asthma screening using mailed parent surveys and medical record review to estimate outcomes of interest, specifically numbers of new asthma diagnoses. RESULTS: Most parents (80%, N = 5116) responded to the asthma screening survey. About 1 in 5 (19.4%, n = 994) parents reported that their children had previously been diagnosed with asthma or reactive airway disease. Letters recommending further evaluation for symptoms suggestive of possible asthma were sent to the parents of 388 children (7.6% of respondents) without known asthma. About half of parents returned postcards stating their intended reaction to the referral recommendation including 52 parents (13.4% of those referred) who thought no further action was necessary. Parent-initiated physician visits occurred in 45 (11.6%) of the 388 referred children. Overall, there were 57 (0.9%, 57/6401) new physician diagnoses of asthma among the screened children in the 6 months following screening: 16 in the referred group and 41 in the group not referred, including 20 in the group whose parents said they had known that their child had asthma, but had no medical record documentation of an asthma diagnosis. The incident asthma diagnosis rate was 1.2% (34/2906; P =.25) in a comparable control group that did not participate in screening. CONCLUSIONS: School-based asthma screening did not increase the incident rate of asthma diagnoses in this community. Parents participated in the screening process, but the percentage of referred children with follow-up medical visits was low.
BACKGROUND: Headaches affect most children and rank third among illness-related causes of school absenteeism. Although the short-term outcome for most children appears favorable, few studies have reported long-term outcome. OBJECTIVE: To evaluate the long-term prognosis of childhood headaches 20 years after initial diagnosis in a cohort of Atlantic Canadian children who had headaches diagnosed in 1983. METHODS: Ninety-five patients with headaches who consulted 1 of the authors in 1983 were previously studied in 1993. The 77 patients contacted in 1993 were followed up in 2003. A standardized interview protocol was used. RESULTS: Sixty (78%) of 77 patients responded (60 of the 95 of the original cohort). At 20-year follow-up, 16 (27%) were headache free, 20 (33%) had tension-type headaches, 10 (17%) had migraine, and 14 (23%) had migraine and tension-type headaches. Having more than 1 headache type was more prevalent than at diagnosis or initial follow-up (P<.001), and headache type varied across time. Of those with headaches at follow-up, 80% (35/44) described their headaches as moderate or severe, although an improvement in headaches was reported by 29 (66%). Tension-type headaches were more likely than migraine to remit (P<.04). Headache severity at diagnosis was predictive of headache outcome at 20 years. During the month before follow-up, nonprescription medications were used by 31 (70%) of those with ongoing headaches, and prescription medications were used by 6 (14%). However, 20 (45%) believed that nonpharmacological methods were most effective. Medication use increased during the 10 years since last follow-up. No patient used selective serotonin receptor agonists (triptans). CONCLUSIONS: Twenty years after diagnosis of pediatric headache, most patients continue to have headache, although the headache classification often changes across time. Most patients report moderate or severe headache and increasingly choose to care for their headaches pharmacologically.
OBJECTIVE: To compare the antipyretic benefit of acetaminophen or ibuprofen monotherapy with an alternating regimen of both drugs in young children aged 6 to 36 months. DESIGN: Randomized, double-blind, parallel-group trial. SETTING: Three primary pediatric community ambulatory centers in central Israel. PARTICIPANTS: A total of 464 children aged 6 to 36 months with fever. INTERVENTION: Infants were assigned to receive either acetaminophen (12.5 mg/kg per dose every 6 hours) (n = 154) or ibuprofen (5 mg/kg per dose every 8 hours) (n = 155) or to receive alternating acetaminophen and ibuprofen (every 4 hours) (n = 155) for 3 days after a loading dose. MAIN OUTCOME MEASURES: Temperature, stress score, amount of antipyretic received, total days that the infant or caregiver was absent from day care or work, respectively, at the 3-day time point, recurrence of fever, and number of emergency department visits. RESULTS: The group given the alternating regimen was characterized by a lower mean temperature, more rapid reduction of fever, receiving less antipyretic medication, less stress, and less absenteeism from day care as compared with the other groups; all of the differences were statistically significant (P< .001). None of the regimens were associated with a significantly higher number of emergency department visits (P = .65) or serious long-term complications (P = .66). The drug used for initial loading had no effect on outcome in any of the groups. CONCLUSIONS: An alternating treatment regimen of acetaminophen (12.5 mg/kg per dose) and ibuprofen (5 mg/kg per dose) every 4 hours for 3 days, regardless of the initial loading medication, is more effective than monotherapy in lowering fever in infants and children.
OBJECTIVES: To measure alcohol and other drug use patterns, adverse consequences of substance use, other high-risk behaviors, and their personal and environmental correlates. DESIGN AND SUBJECTS: The survey was administered in 1989 and 1992 to Minnesota public school students in grades 6, 9, and 12. A comparison sample of school districts that participated in both years consisted of 81% of the state's school districts. District samples were weighted to reflect the proportion of actual enrollment by grade among participating districts. RESULTS: Although alcohol and other drug use declined markedly during the 3-year period studied, the proportion of students who reported at least three adverse consequences of their use was identical in 1989 and 1992: 1% of sixth graders, 7% of ninth graders, and 16% of 12th graders. Alcohol was the primary substance of abuse among students, regardless of age or level of substance involvement. The students with three or more adverse consequences of substance use were defined as "problem users" and compared with other students their age. The most commonly reported consequences of use were tolerance, blackouts, violence, and school or job absenteeism. The problem users were approximately two to seven times more likely to report parental alcohol or other drug problems, physical abuse, and sexual abuse than were students their age with fewer consequences or no history of use. They were also two to 15 times more likely than other students to report such correlates as low self-esteem, emotional distress, antisocial behavior, and suicide attempts. The greatest differences were seen among the youngest students. CONCLUSION: Primary health care workers, social service providers, educators, and other front-line personnel who have contact with youths outside the home need to recognize and respond to behavioral and emotional indicators of risk among adolescents.
CONTEXT: Influenza virus is a major cause of illness, disruption to daily life, and increased use of health care in all age groups. OBJECTIVE: To assess the safety and effectiveness of intranasally administered trivalent, live, attenuated influenza virus (LAIV) vaccine for reducing illness, absenteeism, and health care use among healthy, working adults. DESIGN: Randomized, double-blind, placebo-controlled trial conducted from September 1997 through March 1998. SETTING: Thirteen centers across the United States. PARTICIPANTS: A total of 4561 healthy, working adults aged 18 to 64 years recruited through health insurance plans, at work sites, and from the general population. INTERVENTION: Participants were randomized 2:1 to receive intranasally administered trivalent LAIV vaccine (n = 3041) or placebo (n = 1520) in the fall of 1997. MAIN OUTCOME MEASURES: Episodes of febrile illness, severe febrile illness, febrile upper respiratory tract illness, work loss, and health care use during the peak and total influenza outbreak periods, and adverse events. RESULTS: Recipients of LAIV vaccine were as likely to experience 1 or more febrile illnesses as placebo recipients during peak outbreak periods (13.2% for vaccine vs 14.6% for placebo; P=.19). However, vaccination significantly reduced the numbers of severe febrile illnesses (18.8% reduction; 95% confidence interval [CI], 7.4%-28.8%) and febrile upper respiratory tract illnesses (23.6% reduction; 95% CI, 12.7%-33.2%). Vaccination also led to fewer days of illness across all illness syndromes (22.9% reduction for febrile illnesses; 27.3% reduction for severe febrile illnesses), fewer days of work lost (17.9% reduction for severe febrile illnesses; 28.4% reduction for febrile upper respiratory tract illnesses), and fewer days with health care provider visits (24.8% reduction for severe febrile illnesses; 40.9% reduction for febrile upper respiratory tract illnesses). Use of prescription antibiotics and over-the-counter medications was also reduced across all illness syndromes. Vaccine recipients were more likely to experience runny nose or sore throat during the first 7 days after vaccination, but serious adverse events between the groups were not significantly different. The match between the type A(H3N2) vaccine strain and the predominant circulating virus strain (A/Sydney/05/97[H3N2]) for the 1997-1998 season was poor, suggesting that LAIV provided substantial cross-protection against this variant influenza A virus strain. CONCLUSION: Intranasal trivalent LAIV vaccine was safe and effective in healthy, working adults in a year in which a drifted influenza A virus predominated.
BACKGROUND: Exercise therapy is widely used as an intervention in low-back pain. OBJECTIVES: To evaluate the effectiveness of exercise therapy in adult non-specific acute, subacute and chronic low-back pain versus no treatment and other conservative treatments. SEARCH STRATEGY: The Cochrane Central Register of Controlled Trials (Issue 3, 2004), MEDLINE, EMBASE, PsychInfo, CINAHL databases to October 2004; citation searches and bibliographic reviews of previous systematic reviews. SELECTION CRITERIA: Randomized controlled trials evaluating exercise therapy for adult non-specific low-back pain and measuring pain, function, return-to-work/absenteeism, and/or global improvement outcomes. DATA COLLECTION AND ANALYSIS: Two reviewers independently selected studies and extracted data on study characteristics, quality, and outcomes at short, intermediate, and long-term follow-up. MAIN RESULTS: Sixty-one randomized controlled trials (6390 participants) met inclusion criteria: acute (11), subacute (6) and chronic (43) low-back pain (1 unclear). Evidence was found of effectiveness in chronic populations relative to comparisons at all follow-up periods; pooled mean improvement was 7.3 points (95% CI, 3.7 to 10.9) for pain (out of 100), 2.5 points (1.0 to 3.9) for function (out of 100) at earliest follow-up. In studies investigating patients (i.e. presenting to healthcare providers) mean improvement was 13.3 points (5.5 to 21.1) for pain, 6.9 (2.2 to 11.7) for function, representing significantly greater improvement over studies where participants included those recruited from a general population (e.g. with advertisements). There is some evidence of effectiveness of graded-activity exercise program in subacute low-back pain in occupational settings, though the evidence for other types of exercise therapy in other populations is inconsistent. There was evidence of equal effectiveness relative to comparisons in acute populations [pain: 0.03 points (95% CI, -1.3 to 1.4)]. LIMITATIONS: This review largely reflects limitations of the literature, including low quality studies with heterogeneous outcome measures, inconsistent and poor reporting, and possibility of publication bias. AUTHORS' CONCLUSIONS: Exercise therapy appears to be slightly effective at decreasing pain and improving function in adults with chronic low-back pain, particularly in healthcare populations. In subacute low-back pain there is some evidence that a graded activity program improves absenteeism outcomes, though evidence for other types of exercise is unclear. In acute low-back pain, exercise therapy is as effective as either no treatment or other conservative treatments.
BACKGROUND: The avoidance of menstruation through extended or continuous administration (greater than 28 days of active pills) of combination oral contraceptives (COCs) has gained legitimacy through its use in treating endometriosis, dysmenorrhea, and menstruation-associated symptoms. Avoidance of menstruation through continuous use of COCs for reasons of personal preference may have additional advantages to women, including improved compliance, greater satisfaction, fewer menstrual symptoms, and less menstruation-related absenteeism from work or school. OBJECTIVES: To determine the differences between COCs dosed continuously (greater than 28 days of active pills) compared with traditional cyclic dosing (21 days of active pills and 7 days of placebo). Our hypothesis was that continuously administered COCs have equivalent efficacy and safety but improved bleeding profiles, amenorrhea rates, adherence, continuation, participant satisfaction, and menstrual symptoms compared with cyclic COCs. SEARCH STRATEGY: We searched computerized databases (Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, POPLINE, LILACS) for trials using continuous or extended COCs during the years 1966 to 2005. We also searched the references in review articles and publications identified for inclusion in the protocol. Investigators were contacted regarding additional references. SELECTION CRITERIA: All randomized controlled trials in any language comparing continuous (greater than 28 days of active pills) versus traditional cyclic administration (21 days of active pills and 7 days of placebo) of COCs for contraception. DATA COLLECTION AND ANALYSIS: Titles and abstracts identified from the literature searches were assessed for potential inclusion. Data were extracted onto data collection forms and then entered into RevMan 4.2. Peto odds ratios with 95% confidence intervals were calculated for all outcomes for dichotomous outcomes. Weighted mean difference was calculated for continuous outcomes. The trials were critically appraised by examining the following factors: study design, blinding, randomization method, group allocation concealment, exclusions after randomization, loss to follow-up, and early discontinuation. Because the included trials did not have a standard treatment (type of pill and time length for continuous dosing), we could not aggregate data into meta-analysis. MAIN RESULTS: Six randomized controlled trials met our inclusion criteria. Study findings were similar between 28-day and extended cycles in regard to contraceptive efficacy (i.e., pregnancy rates) and safety profiles. When compliance was reported, no difference between 28-day and extended cycles was found. Participants reported high satisfaction with both dosing regimens, but this was not an outcome universally studied. Overall discontinuation and discontinuation for bleeding problems were not uniformly higher in either group in most studies. The few studies that reported menstrual symptoms found that the extended cycle group fared better in terms of headaches, genital irritation, tiredness, bloating, and menstrual pain. Five out of the six studies found that bleeding patterns were either equivalent between groups or improved with continuous-dosing regimens. Endometrial lining assessments by ultrasound were done in a small number of participants but all endometrial stripe measurements were less than 5 mm. AUTHORS' CONCLUSIONS: Evidence from existing randomized control trials comparing COCs given continuously (greater than 28 days of active pills) to traditional monthly cyclic dosing (21 days of active pills and 7 days of placebo) is of good quality. However, the variations in type of pill and time length for continuous dosing make direct comparisons between regimens impossible. Future studies should choose a previously described type of pill and dosing regimen. More attention needs to be directed towards participant satisfaction and menstruation-associated symptoms.
BACKGROUND: Irritable bowel syndrome (IBS), a disorder of altered bowel habits associated with abdominal pain or discomfort. The pain, discomfort, and impairment from IBS often lead to healthcare medical consultation (Talley 1997) and workplace absenteeism, and associated economic costs (Leong 2003). A recent randomized controlled trial shows variable results but no clear evidence in support of acupuncture as an effective treatment for IBS (Fireman 2001). OBJECTIVES: The objective of this systematic review is to determine whether acupuncture is more effective than no treatment, more effective than 'sham' (placebo) acupuncture, and as effective as other interventions used to treat irritable bowel syndrome. Adverse events associated with acupuncture were also assessed. SEARCH STRATEGY: The following electronic bibliographic databases were searched irrespective of language, date of publication, and publication status: MEDLINE, the Cochrane Central Register of Controlled Trials (CENTRAL) on The Cochrane Library, EMBASE, the Chinese Biomedical Database, the Cumulative Index to Nursing and Allied Health (CINAHL), and the Allied and Complementary Medicine Database (AMED). References in relevant reviews and RCTs were screened by hand. The last date for searching for studies was 7 February 2006. SELECTION CRITERIA: Published reports of randomized controlled trials (RCTs) and quasi-randomised trials of acupuncture therapy for IBS. DATA COLLECTION AND ANALYSIS: All eligible records identified were dually evaluated for eligibility and dually abstracted. Methodological quality was assessed using the Jadad scale and the Linde Internal Validity Scale. Data from individual trials were combined for meta-analysis when the interventions were sufficiently similar. Heterogeneity was assessed using the I squared statistic. MAIN RESULTS: Six trials were included. The proportion of responders, as assessed by either the global symptom score or the patient-determined treatment success rate, did not show a significant difference between the acupuncture and the sham acupuncture group with a pooled relative risk of 1.28 (95% CI 0.83 to 1.98; n=109). Acupuncture treatment was also not significantly more effective than sham acupuncture for overall general well-being, individual symptoms (e.g., abdominal pain, defecation difficulties, diarrhea, and bloating), the number of improved patients assessed by blinded clinician, or the EuroQol score. For two of the studies without a sham control, acupuncture was more effective than control treatment for the improvement of symptoms: acupuncture versus herbal medication with a RR of 1.14(95% CI 1.00 to 1.31; n=132); acupuncture plus psychotherapy versus psychotherapy alone with a RR of 1.20 (95% CI 1.03 to 1.39; n=100). When the effect of ear acupuncture treatment was compared to an unclearly specified combination of one or more of the drugs diazepam, perphenazine or domperidone, the difference was not statistically significant with a RR of 1.49(95% CI 0.94 to 2.34; n=48). AUTHORS' CONCLUSIONS: Most of the trials included in this review were of poor quality and were heterogeneous in terms of interventions, controls, and outcomes measured. With the exception of one outcome in common between two trials, data were not combined. Therefore, it is still inconclusive whether acupuncture is more effective than sham acupuncture or other interventions for treating IBS.
