A headache protocol for nurses: effectiveness and efficiency.

To test the effectiveness and efficiency of a nurse-administered protocol for headache in the primary care setting, we conducted a prospective controlled trial. Two hundred three randomly allocated patients were evaluated by nurses using the protocol who managed independently 55.2% of the patients and received physician consultation on the others. A total of 193 patients were randomly allocated to the physician-control group. Nurse-protocol group patients experienced equivalent symptomatic relief and expressed significantly greater satisfaction with the care they had received than did patients in the physician-control group. A retrospective study of the presenting findings in patients with serious diseases of the CNS provided evidence supporting the safety of the protocol logic. We conclude that nurse-protocol management of headache in this primary care practice was effective and efficient.

Peer review by criteria mapping: criteria for diabetes mellitus. The use of decision-making in chart audit.

The UCLA Experimental Medical Care Review Organization (EMCRO), in an attempt to minimize the problem of applying a general list of criteria to each patient with a specific condition, has developed a method called Criteria Mapping. This method uses sequential judgments based on the specific clinical data for the individual patient to assess the quality of care by medical record audit. The method does not penalize the physician for omitting unnecessary procedures by allowing alternate decisions when appropriate, and provides supporting reference materials to allow nonphysicians to make reliable medical interpretations of the data in medical records. It is expected that this method will more accurately reflect the physicians' intentions, and that process, when measured by this approach, may correlate better with the outcome of medical care.

Protocol management of dysuria, urinary frequency, and vaginal discharge.

A proctocol to be administered by nurses for the management of dysuria, frequent urination, and vaginal discharge was validated. In a randomized, controlled trial, 146 women were seen by both nurse and physician and then assigned to either the nurse-proctocol treatment plan or the physician treatment plan. The clinical data collected by the nurse showed no important differences from the physicians' data. The protocol recommended that 89 percent of the patients be sent home without seeing the physician. The physicians agreed with the protocol-recommended disposition in all but two cases. All patients with complications were appropriately referred to the physician. In follow-up, more than 95 percent of both groups reported symptomatic improvement, and repeat urine cultures were negative. We conclude that the protocol can be accurately administered, makes sound recommendations, is safe, and efficiently saves physician time.

Nurse-protocol management of low back pain. Outcomes, patient satisfaction and efficiency of primary care.

To test the validity of a nurse-administered protocol for low back pain, a prospective trial of 419 patients was undertaken in a walk-in clinic. In all, 222 patients were randomly allocated to a "nurse-protocol group" in which they were evaluated by one of five nurses using the protocol; the nurses independently managed 53 percent of the patients and referred to a physician patients with potentially complex conditions. In addition, 197 patients in a randomly allocated control group were managed by one of 32 physicians. Care in the experimental and control groups was compared by follow-up telephone contact and by a four-month chart review. There was no significant difference in symptomatic relief or the development of serious disease in the two groups. Nurse-protocol patients expressed greater satisfaction with the care they had received; patient satisfaction correlated positively with symptom relief. In over 95 percent of the patients, there were noncomplex, nonserious, nonchronic conditions as the cause of back pain. We conclude that nurse-protocol management of this generally benign condition in a primary care setting is both effective and efficient.

Upper-respiratory tract complaint protocol for physician-extenders.

A protocol for upper-respiratory tract complaints was administered to 226 patients in a walk-in clinic. The protocol, for use by a physician-extender in conjunction with a physician, specified the collection of data necessary for management. A decision-making algorithm separated the major causes of upper respiratory infection (URI) complaints and led to one of four plans: a physician referral, a culture only, antibiotic treatment, or symptomatic treatment only. Each patient was seen by a physician following the health assistant's interview. Of 226 patients, 96 (42 percent) would have been sent home by the protocol without seeing the physician. None of these had a complication of URI. Sixteen (seven percent) of the 226 had serious complications - all would have been referred to the physician. The protocol proved to be safe and efficient, acceptable to patients, and a reliable approach to physician-extender management of URI.

Prevention of gram-negative bacillary pneumonia using aerosol polymyxin as prophylaxis. I. Effect on the colonization pattern of the upper respiratory tract of seriously ill patients.

A prospective study used polymyxin B by aerosol to reduce colonization of the upper respiratory tract with nosocomial gram-negative bacilli. 58 high-risk patients from the Respiratory-Surgical Intensive Care Unit entered the trial. 33 were randomly selected to receive 2.5 mg/kg/day of polymyxin B by hand atomizer into the pharynx, and tracheal tube if present. 17 of 25 control patients became colonized with gram-negative bacilli as compared with 7 of 33 polymyxin-treated patients (p < 0.01). Control patients became colonized with a total of 33 gram-negative bacilli: 3 were Pseudomonas aeruginosa, 21 were species of Enterobacteriaceae. The polymyxin-treated patients became colonized with a total of 11 gram-negative bacilli: no P. aeruginosa and only 3 species of Enterobacteriaceae were recovered. Colonization increased with duration in Respiratory-Surgical Intensive Care Unit and with time of required controlled ventilation. Polymyxin most effectively prevented the increase in colonization in treated patients who stayed in the Respiratory-Surgical Intensive Care Unit for longer than 1 wk and who required controlled ventilation for at least 72 h.
