A comprehensive mental health nursing assessment: variability of content in practice

Assessment is the foundation of mental health nursing practice, but little is known of how it is undertaken. This paper explores how mental health nurses describe the content of a comprehensive mental health nursing assessment. Eighteen nurses who worked in inpatient and community settings either as clinicians or managers, ranging from new graduates to nurses with greater than 20 years of experience, were interviewed and asked to describe the content of a comprehensive mental health nursing assessment. Transcribed interviews were analysed using a grounded theory methodology. The primary theme to emerge was one of variability. Most respondents hesitated and then identified different content areas that needed to be assessed as part of a comprehensive mental health nursing assessment. If the areas that are being assessed vary between nurses, then logically the types of interventions being offered will also vary. These results have implications for the education of nurses, their clinical practice, ongoing supervision and research into contemporary mental health nursing practice.

What is the process of a comprehensive mental health nursing assessment? Results from a qualitative study

BACKGROUND

It is a truism that nursing care must be informed by assessment, otherwise how can one know what care is required or that it has been successfully delivered? Yet, little is known about the process of comprehensive mental health nursing assessment in practice. If the education of mental health nurses is to be effective, it is essential that the key content of, and the processes involved in carrying out a mental health nursing assessment in practice are able to be articulated to learners.

AIM

To identify the processes of assessment that occur in mental health nursing practice based on interviews with mental health nurses working in clinical and management roles in clinical areas.

METHOD

Interviews were undertaken with 18 nurses who worked in inpatient and community mental health settings either as clinicians or managers. The nurses ranged from new graduates to those with more than 20 years of experience.

FINDINGS AND DISCUSSION

Clear processes were reported to be involved in undertaking a comprehensive mental health nursing assessment in practice, with three main themes emerging during analysis. First is the importance of engaging the patient; second is tell me what the problem is? with one subtheme reconcile inconsistencies; and finally, the ongoing nature of the assessment process.

CONCLUSION

Common processes emerged when the nurses described their individual approaches to undertaking comprehensive mental health assessment. The results have important policy implications for the educational preparation of mental health nurses, their ongoing supervision and further research into contemporary mental health nursing practice.

The Teamwork Study: enhancing the role of non-GP staff in chronic disease management in general practice

There is evidence for a team-based approach in the management of chronic disease in primary health care. However, the standard of care is variable, probably reflecting the limited organisational capacity of health services to provide the necessary structured and organised care for this group of patients. This study aimed to evaluate the impact of a structured intervention involving non-GP staff in GP practices on the quality of care for patients with diabetes or cardiovascular disease. A cluster randomised trial was undertaken across 60 GP practices. The intervention was implemented in 30 practices with staff and patients interviewed at baseline and at 12–15 months follow up. The change in team roles was evaluated using a questionnaire completed by practice staff. The quality of care was evaluated using the Patient Assessment of Chronic Illness Care questionnaire. We found that although the team roles of staff improved in the intervention practices and there were significant differences between practices, there was no significant difference between those in the intervention and control groups in patient-assessed quality of care after adjusting for baseline-level score and covariates at the 12-month follow up. Practice team roles were not significantly associated with change in Patient Assessment of Chronic Illness Care scores. Patients with multiple conditions were more likely to assess their quality of care to be better. Thus, although previous research has shown a cross-sectional association between team work and quality of care, we were unable to replicate these findings in the present study. These results may be indicative of insufficient time for organisational change to result in improved patient-assessed quality of care, or because non-GP staff roles were not sufficiently focussed on the aspects of care assessed. The findings provide important information for researchers when designing similar studies.

Facilitating teamwork in general practice: moving from theory to practice

The aims of this paper are to describe the development of an intervention to improve teamwork and systems in general practice that support the care of patients with diabetes, ischaemic heart disease and hypertension and to identify the challenges to implementing the intervention. Effective teamwork in general practice encompasses general practitioners (GP), clinical and non-clinical staff, each with clearly defined roles and opportunities to provide feedback and input into how the practice is run and chronic disease managed. The intervention implemented in this study provided an opportunity for key members of general practice teams to work with a facilitator on changes to improve teamwork over three practice visits over 6–12 months. Facilitators had experience in practice support and goal setting, an understanding of the Medicare Items and knowledge about teamwork and systems. The visits focussed on the specific needs and capacities of each practice, assisting the team to set manageable goals and building systems that best utilise the systemic and human resources available. Successful implementation of sustained change depended on strong leadership in the practice and cooperation between team members as well as clear and achievable goals being set. Structured facilitation of teamwork in general practice should focus on goal setting and the development of leadership and communication rather than delivery of information or resources.

Radical surgery with omental flap for uncontrolled locally recurrent breast cancer

BACKGROUND

Uncontrolled chest wall disease due to breast cancer is a highly morbid condition causing pain, ulceration, malodour and the need for frequent dressings. Aggressive surgical approaches are rarely justified because most patients will succumb to metastatic breast cancer within a short period. A highly selected group of patients with minimal or no evidence of metastatic disease and good performance status may benefit from radical chest wall surgery. Omental transposition flaps are ideal for reconstructing extensive surgical defects following chest wall surgery.

METHODS

A retrospective review was carried out of 61 female patients treated consecutively between 1980 and 1995. The surgical technique is described herein.

RESULTS

All patients were symptomatic preoperatively. Symptoms included ulceration (80%), pain (44%) and malodour (40%). Twenty-nine patients had uncontrolled local recurrence following initial treatment for locally advanced breast cancer and 32 patients developed uncontrolled recurrence after treatment for operable breast cancer by mastectomy or conservation surgery. Median survival following chest wall surgery was 21 months and the median local recurrence-free interval was 20 months. Morbidity was -limited. There were no cases of major flap loss. Twenty-nine patients (48%) had no further local disease. Eighteen patients (30%) developed soft-tissue recurrence at the edge of the omental flap or in surrounding skin and 14 (23%) developed recurrence beneath the flap.

CONCLUSION

In a highly selected group of patients with symptomatic uncontrolled chest wall recurrence who are fit and have an expectation of at least moderate-term survival, radical chest wall surgery and omental flap transposition offers excellent palliation and local control in the majority of patients

Mallory-Weiss syndrome: possible link to water immersion and subsequent air flight

Mallory-Weiss Syndrome (MWS) lesions account for up to 15 per cent of upper gastrointestinal bleeding episodes. Typically these lesions present as a consequence of vomiting that is often associated with alcoholism. Recently other conditions such as pregnancy, migraine, hiatal hernia, gastric ulcer, biliary disease, and various medications have been associated with MWS. We report on a 32-year-old male who developed a MSW lesion after a prolonged period of swimming followed by an extended commercial airplane flight. The hemodynamic changes associated with swimming (increased central distribution of blood volume) and the pressure changes in commercial aircraft (a reduction of 0.3 atmospheres of pressure) are discussed. We conclude that the combination of these factors contributed to the development of a MWS lesion and gastrointestinal bleeding in this patient. We recommend that both air travel and athletic activities be considered as possible contributing factors in the evaluation of the cause of new-onset gastrointestinal bleeding.

The treatment of gastroesophageal reflux disease with laparoscopic Nissen fundoplication: prospective evaluation of 100 patients with "typical" symptoms

OBJECTIVE

To evaluate prospectively the outcome of laparoscopic fundoplication in a large cohort of patients with typical symptoms of gastroesophageal reflux.

SUMMARY BACKGROUND DATA

The development of laparoscopic fundoplication over the past several years has resulted in renewed interest in the surgical treatment of gastroesophageal reflux disease (GERD).

METHODS

One hundred patients with typical symptoms of GERD were studied. The study was limited to patients with positive 24-hour pH studies and "typical" symptoms of GERD. Laparoscopic fundoplication was performed when clinical assessment suggested adequate esophageal motility and length. Outcome measures included assessment of the relief of the primary symptom responsible for surgery; the patient's and the physician's evaluation of outcome; quality of life evaluation; repeated upper endoscopy in 30 patients with presurgical esophagitis; and postsurgical physiologic studies in 28 unselected patients, consisting of 24-hour esophageal pH and lower esophageal sphincter manometry.

RESULTS

Relief of the primary symptom responsible for surgery was achieved in 96% of patients at a mean follow-up of 21 months. Seventy-one patients were asymptomatic, 24 had minor gastrointestinal symptoms not requiring medical therapy, 3 had gastrointestinal symptoms requiring medical therapy, and 2 were worsened by the procedure. Eighty-three patients considered themselves cured, 11 were improved, and 1 was worse. Occasional difficulty swallowing not present before surgery occurred in 7 patients at 3 months, and decreased to 2 patients by 12 months after surgery. There were no deaths. Clinically significant complications occurred in four patients. Median hospital stay was 3 days, decreasing from 6.3 in the first 10 patients to 2.3 in the last 10 patients. Endoscopic esophagitis healed in 28 of 30 patients who had presurgical esophagitis and returned for follow-up endoscopy. Twenty-four-hour esophageal acid exposure had returned to normal in 26 of 28 patients studied after surgery. Lower esophageal sphincter pressures had also returned to normal in all patients, increasing from a median of 5.1 mmHg to 14.9 mmHg.

CONCLUSIONS

Laparoscopic Nissen fundoplication provides an excellent symptomatic and physiologic outcome in patients with proven gastroesophageal reflux and "typical" symptoms. This can be achieved with a hospital stay of 48 hours and a low incidence of postsurgical complications.

ERCC1 mRNA levels complement thymidylate synthase mRNA levels in predicting response and survival for gastric cancer patients receiving combination cisplatin and fluorouracil chemotherapy

PURPOSE

We have previously shown that relative thymidylate synthase (TS) mRNA levels in primary gastric adenocarcinomas treated with fluorouracil (5-FU) and cisplatin are inversely associated with response and survival. This is a presumed function of TS as a target for 5-FU activity. We now test the hypotheses that the relative mRNA level of the excision repair cross-complementing (ERCC1) gene is inversely associated with response and survival as an independent function of cisplatin efficacy.

PATIENTS AND METHODS

Patients had intact, untreated, primary gastric adenocarcinoma cancer and were evaluated for eligibility on a preoperative cisplatin infusion-5-FU protocol. cDNA, derived from primary gastric tumors before chemotherapy, was used to determine ERCC1 mRNA levels, expressed as the ratio of polymerase chain reaction (PCR) product of the ERCC1 gene and the beta-actin gene.

RESULTS

The median ERCC1 mRNA level from 38 primary gastric cancers (33 assessable for response) was 5.8 x 10(-3) (range, 1.8 x 10(-3) to 19.5 x 10(-3)). Of 17 responding patients, 13 (76%) were less than or equal to 5.8 x 10(-3) and four were greater than 5.8 x 10(-3) (P = .003). The median survival for patients with ERCC1 mRNA levels less than or equal to 5.8 x 10(-3) has not been reached, whereas for those greater than 5.8 x 10(-3) it was 5.4 months (P = .034). The median TS mRNA level, 3.7 x 10(-3) (range, 0.9 to 18.9) also segregated responsive versus resistant tumors (P = .024). With both ERCC1 and TS mRNA levels below their medians, 11 of 13 patients (85%) responded; with both ERCC1 and TS mRNA levels above their medians, two of 10 patients (20%) responded (P = .003).

CONCLUSION

Considered separately, either ERCC1 or TS mRNA levels in a primary gastric adenocarcinoma has a statistically significant relationship to response. ERCC1 mRNA levels have a statistically significant association with survival; in this cohort TS mRNA levels did not reach statistically significant association with survival as in our previous publication. Whether these molecular parameters are independent of each other as predictors of outcome remains to be determined.

Inflammation and specialized intestinal metaplasia of cardiac mucosa is a manifestation of gastroesophageal reflux disease

OBJECTIVE

The purpose of the study was to test the hypothesis that cardiac mucosa, carditis, and specialized intestinal metaplasia at an endoscopically normal-appearing cardia are manifestations of gastroesophageal reflux disease.

SUMMARY BACKGROUND DATA

In the absence of esophageal mucosal injury, the diagnosis of gastroesophageal reflux disease currently rests on 24-hour pH monitoring. Histologic examination of the esophagus is not useful. The recent identification of specialized intestinal metaplasia at the cardia, along with the observation that it occurs in inflamed cardiac mucosa, led the authors to focus on the type and condition of the mucosa at the gastroesophageal junction and its relation to gastroesophageal reflux disease.

METHODS

Three hundred thirty-four consecutive patients with symptoms of foregut disease, no evidence of columnar-lined esophagus, and no history of gastric or esophageal surgery were evaluated by 1) endoscopic biopsies above, at, and below the gastroesophageal junction; 2) esophageal motility; and 3) 24-hour esophageal pH monitoring. The patients were divided into groups depending on the histologic presence of cardiac epithelium with and without inflammation or associated intestinal metaplasia. Markers of gastroesophageal reflux disease were compared between groups (i.e., lower esophageal sphincter characteristics, esophageal acid exposure, the presence of endoscopic erosive esophagitis, and hiatal hernia).

RESULTS

When cardiac epithelium was found, it was inflamed in 96% of the patients. The presence of cardiac epithelium and carditis was associated with deterioration of lower esophageal sphincter characteristics and increased esophageal acid exposure. Esophagitis occurred more commonly in patients with carditis whose sphincter, on manometry, was structurally defective. Specialized intestinal metaplasia at the cardia was only seen in inflamed cardiac mucosa, and its prevalence increased both with increasing acid exposure and with the presence of esophagitis.

CONCLUSION

The findings of cardiac mucosa, carditis, and intestinal metaplasia in an endoscopically normal-appearing gastroesophageal junction are histologic indicators of gastroesophageal reflux disease. These findings may be among the earliest signs of gastroesophageal reflux and contribute to the authors understanding of the pathophysiology of the disease process.

Nissen fundoplication prevents shortening of the sphincter during gastric distention

OBJECTIVE

To determine the dynamic effects of a Nissen fundoplication on a volume-stressed lower esophageal sphincter (LES).

DESIGN

Before and after experimental study in 10 baboons.

SETTING

University animal research unit.

INTERVENTIONS

Continuous manometric evaluation of the esophagus, cardia, and stomach during distention of the stomach with water. Slow motorized pull-through of the LES after each successive intragastric increment of 50 mL of water. Tests were performed again after a Nissen fundoplication.

MAIN OUTCOME MEASURES

Lower esophageal sphincter length and frequency of common cavity episodes after each volume increment. The pressure and intragastric volume at the yield point are defined as the point of permanent loss of the gastroesophageal pressure gradient.

RESULTS

Gastric distention of the stomach with water resulted in a progressive decrease in LES length and competency. The median +/- interquartile range LES length decreased by 1.5 +/- 0.3 mm for every 1-mm Hg increase in gastric pressure before fundoplication and by 0.2 +/- 0.1 mm after fundoplication (P < .02). With gastric distention there was an indirect correlation between the degree of LES length and the frequency of reflux episodes (r = -0.70). This correlation was abolished by a Nissen fundoplication (r = -0.31). The median +/- interquartile range frequency of common cavity episodes (2.19 +/- 2.05 episodes per minute) before fundoplication decreased significantly (P < .001) to 0 +/- 0.59 episodes per minute after fundoplication. The median +/- interquartile range yield pressure (13 +/- 9 mm Hg) and yield volume (825 +/- 855 mL) were significantly (P < .01) improved after Nissen fundoplication to 39 +/- 36 mm Hg and 1250 +/- 750 mL, respectively.

CONCLUSION

By preventing sphincter shortening, a Nissen fundoplication improves competency of the LES to progressive degrees of gastric distention.

Systemic chemotherapy for gastric carcinoma followed by postoperative intraperitoneal therapy: a final report

BACKGROUND

Because only approximately 50% of gastric carcinomas are resectable for cure, the authors hypothesized that effective systemic preoperative (neoadjuvant) chemotherapy, aimed at decreasing the size and extent of the primary tumor and eradicating distant microscopic disease, may increase the rate of resectability and have a greater impact on survival than postoperative (adjuvant) treatment alone. In addition, because the peritoneal cavity is the most common site of first recurrence after successful gastric cancer resection, intraperitoneal (IP) chemotherapy seemed a logical choice for postoperative (adjuvant) treatment.

METHODS

Fifty-nine patients with invasive primary gastric adenocarcinoma who were deemed resectable for cure entered a clinical trial that called for 2 cycles of protracted infusion 5-fluorouracil with weekly leucovorin and cisplatin chemotherapy followed by surgery. Approximately 3-4 weeks after potentially curative surgery, patients were scheduled to receive two cycles of IP 5-fluoro-2'deoxyuridine and cisplatin.

RESULTS

Of the 59 patients studied, 58 (98%) received both cycles of systemic chemotherapy. Fifty-six patients (95%) underwent surgery: 40 patients (71%) had resections intended to cure for Stage 0-IIIB disease, 15 patients (27%) had palliative surgery for Stage IV gastric carcinoma, and one patient died intraoperatively without being staged. Two patients refused surgery, and the remaining patient died of progressive disease prior to surgery. Thirty-one of the 40 patients who underwent curative surgery completed both cycles of postoperative IP therapy; 4 patients received only 1 cycle. Three patients (5%) died secondary to treatment complications. There were two operative deaths, and one patient died of peritonitis associated with Grade 4 granulocytopenia. Nine of the 40 patients (23%) whose carcinomas were resected for cure had recurrent carcinoma. With a median follow-up period now exceeding 45 months, the calculated median survival for the 59 patients entered into the trial is >4 years.

CONCLUSIONS

This program of preoperative systemic and postoperative IP chemotherapy has been found to be safe and appears to decrease gastric carcinoma recurrence rates and increase survival compared with historic controls.

Thymidylate synthase mRNA level in adenocarcinoma of the stomach: a predictor for primary tumor response and overall survival

PURPOSE

We tested the hypothesis that polymerase chain reaction (PCR) quantitation of the enzyme thymidylate synthase (TS) within a primary adenocarcinoma of the stomach, has an inverse relationship to response and survival for patients who receive fluorouracil (5FU)-based chemotherapy.

PATIENTS AND METHODS

Before systemic chemotherapy, the genetic expression of TS (TSmRNA level) was determined using a PCR method. Gene expression was calculated by determining the ratio between the amount of radiolabeled PCR product with the linear amplification range of the TS gene and the beta-actin gene. Chemotherapy consisted of two cycles of protracted infusion (PI) 5FU 200 mg/m2/d administered for 3 weeks with leucovorin 20 mg/m2/w. Cisplatin 100 mg/m2 was administered on day 1.

RESULTS

Sixty-five patients with primary gastric cancer had a median TS mRNA level of 4.6 x 10(-3) (range, 0.9 to 20.1 x 10(-3)). Thirty-five percent of patients had measurable responses in their primary tumors. The mean gastric cancer TSmRNA level in responding and resistant patients is statistically significant (P < .001). The median survival time was 43+ months for treated patients with TSmRNA levels less than the median and 6 months for those with TS m-RNA levels greater than the median (P = .003).

CONCLUSION

The genetic expression of TS (TSmRNA level) influences response to 5FU-based chemotherapy and survival for a cohort of patients with primary gastric cancer. Confirmation of these data could lead to therapeutic decisions based on specific molecular properties within a tumor.

Reasons for conversion from laparoscopic to open cholecystectomy in an urban teaching hospital

BACKGROUND

Although laparoscopic cholecystectomy has replaced open cholecystectomy for the majority of patients, it is clear that a substantial minority will require laparotomy for safe and successful removal of the gallbladder.

PATIENTS AND METHODS

Seven hundred forty-six laparoscopic cholecystectomies performed at LAC+USC Medical Center for January 1991 to May 1993 were retrospectively reviewed. Hospital stay, laboratory values, and complications, as well as the need for and reason for conversion to open cholecystectomy were recorded. There were 661 females and 85 males, with a mean age of 38 years (range 15 to 92).

RESULTS

One hundred one (14%) of the 746 patients were converted to open cholecystectomy. Difficult dissection secondary to inflammation or adhesions and the need to treat common-bile-duct stones were the most common reasons for conversion. Patients requiring conversion to open cholecystectomy were more likely to have been admitted through the emergency department (72% versus 46%, P < 0.0001), have had prolonged hospital stays prior to surgery (mean time from admission to surgery 4.4 days versus 2.8 days, P < 0.0001), and to have had a thickened gallbladder wall on preoperative ultrasound (54% versus 20%, P < 0.001).

CONCLUSIONS

The most common reasons for conversion to open cholecystectomy are inflammation and adhesions secondary to severe acute and chronic disease and/or the need for clearance of the common bile duct. Patients who were admitted to the emergency department, particularly if they were managed nonoperatively for a period of time and had a preoperative diagnosis of acute cholecystitis, were more likely to require conversion to open cholecystectomy.
