· An electronic version of our quality of life measure, LCSS-QL, has been developed that uses a hand-held Pocket PC to enhance the ease of use of incorporating this assessment into clinical trials and patient care. The goal of this version is to assist in making quality of life evaluation easier to perform in a practice setting, as well as in clinical trials, by using the assistance of a hand-held computer.
· The hand-held pc is used for the gathering of data and is then linked to a desktop or laptop computer for an immediate summary report. It "syncs" to the desktop effortlessly. The patient data are then stored on the desktop, and patients on particular studies have their data held in a file. Different sites can electronically transmit their data to a central site for analysis. The individual patient information is portrayed on the desktop as either bar graphs or line graphs (showing change over time), allowing the health professional to know - and act upon - the patient's scores and trends. Both the patient scale and the optional observer scale are on the hand held, as well as both Karnofsky and ECOG performance status scales. A color printer is used for an instant summary report with scores and trend lines.
The LCSS has been programmed into the Windows-based PDA operating
system devices (thus, hand helds that are not Palm-based). The reason
for the choice of the Pocket PC was that the operating system is
more powerful and is more easily adapted for such custom programming.
This system eliminates several practical impediments to efficient
assessment of quality of life: 1) the location of various paper
instruments; 2) the measuring of score ratings; 3) the transcription
of data, with the potential of measurement error, such as transposing
numbers; 4) the difficulty of displaying of quality of life information
over time; 5) the collation of data for analysis; and 6) the maintenance
of patient confidentiality (with use of passwording).

The Lung Cancer Symptom Scale (LCSS) is a site-specific (site of
the primary cancer) health-related quality of life (HRQL) questionnaire
for individuals with lung cancer. The LCSS was designed as a written
measure for use in clinical therapeutic trials and in clinical practice
for patients with lung cancer undergoing treatment. The philosophy
behind the development of the LCSS was to provide a practical measure
that would reduce patient and staff burden in repeated measurement
of HRQL during the course of a trial or during treatment, and would
concentrate in detail on those aspects of quality of life most likely
to be affected by treatment interventions.
The LCSS (paper format) has been used for over 15 years
in many countries and on six continents. It was evaluated for feasibility,
reliability, and validity in nearly 1,000 lung cancer patients at
eight cancer centers in the U.S. and Canada. The outcomes were quite
favorable, and results have been published in several peer-reviewed
journals, such as Cancer, European Journal of Cancer, Lung Cancer,
and Supportive Care in Cancer.
At a recent conference in Naples, Italy (December 2002), the consensus
was that HRQL assessment needs to be more feasible, with better
patient completion rates and less measurement error. Although the
completion rate for the brief 9-item patient LCSS has been good,
there is the potential for measurement error with use of the hand
scored visual analogue scales.
